There have been several "kabooms" of S&W AR's shown on these forums since I've joined. S&W almost always blames the ammo and offers to sell a new rifle to the owner at cost. Unfortunately, what they consider cost with a Sport is about what you can buy one for online. S&W knows that since no one was injured that this incident will never see a court.

Federal will blame the rifle when and if S&W contacts them..

The OP will never see the original rifle again. Sorry.

I have two S&W AR's that have had the snot shot out of them, and I have total faith that I can continue to do so. Things happen.
